摘要
通过Excel设置的分光比计算模板对有线电视网络中光分路数的内在规律进行探析,从而明了有线电视网络中最佳光分路数随着光发射机输出功率与光接收机的输入电平的改变而改变,揭开了有线电视网络所传输的光链路总(或平均单路传输)距离所对应的最佳光分路数设计的规律与思路,恰当应用这一规律与思路,能有效地提高网络的性价比。
split ratio set by EXCEL template for calculation of optical cable network in the inner regularity of large ones to understand the cable television network in the large ones with the best optical output power of optical transmitter and optical receiver input level is changed;opened the cable TV transmission network optical link total(or average one-way transmission) from the corresponding large ones the best optical design rules and ideas,appropriate application of this law and ideas,can effectively improve the network cost.
